  • When performance issues arise, a BA should ask which reports or dashboards are slow.
  • Ask whether the issue occurs on all visuals or specific pages.
  • Check if the problem happens in both Power BI Desktop and Service.
  • Ask about dataset size and whether DirectQuery or Import mode is used.
  • Inquire about refresh times and whether incremental refresh is implemented.
  • Ask if multiple users experience slowness simultaneously.
  • Check if complex DAX measures or high-cardinality columns are involved.
  • Finally, confirm any recent changes to the model, queries, or source data.
